Question 561

HOTSPOT

Corporate headquarters provided your office a portion of their class B subnet to use at a new office location.

Range Given: 172.30.232.0/24

Sales 57 devices

HR 23 devices

IT 12 devices

Finance 32 devices

Marketing 9 devices

INSTRUCTIONS

Allocate the minimum number of addresses (using CIDR notation) needed to accommodate each department.

After accommodating each department, identify the unused portion of the subnet by responding to the question on the

graphic.

All drop downs must be filled.

If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.

Hot Area:

Correct Answer:

Sales network – /26 – This will provide up to 62 usable IP addresses (64-2 for subnet and broadcast IP)

HR network - /27 – This will provide for up to 30usable IP’s (32-2)

IT - /28 – This will provide for up to 14 usable IP’s (16-2)

Finance - /26 – Note that a /27 is 32 IP addresses but 2 of those are reserved for the network and broadcast IP’s and can’t

be used for hosts.

Marketing - /28

If we add up how many IP blocks are used that is 64+32+16+64+16=192.

A /24 contains 256 IP addresses, so 256-192=64.

So the last unused box should be a /26, which equates to 64 addresses
